- Abstract
Objective: To compare the linear dimensional change occurring between the antero-posterior and mediolateral reference points marked on the heat- polymerized denture base resin between two groups formed with and without the addition of multi-walled carbon nanotubes in the posterior palatal seal region and mid palatine area on maxillary edentulous brass model. Method: Standard edentulous maxillary brass model, with 4 reference points [at incisive papilla (A), mid-palatal area in front of posterior palatal seal region (B), left and right tuberosities (C and D)] was made to fabricate a total of 10 denture bases. On the model, wax templates in the shape of posterior palatal seal (PPS) and mid palatine raphe were made to standardize the quantity of modified material incorporated in the PPS area and the mid palatine area i.e. acrylic mixed with 1 wt% of carbon nanotube. A control group with no incorporation of the modified material was also created. After denture base fabrication with incorporated modified material, the antero-posterior and the medio-lateral distance, between points A and B and points C and D, was measured with Digital Vernier Caliper and compared with the control group. Results: There was statistically significant difference found between the control and the incorporated carbon nanotube group when compared using unpaired t-test. Conclusion: Addition of carbon nanotubes in denture base acrylic resin showed significant linear dimensional change for this study.
